Hetero-functional azo reactive dyes applied on cellulosic fabric and dyeing conditions optimization to enhance the dyeing properties

New dyestuff moieties are introduced in the textile industry to upgrade quality and aesthetic properties of dyed fabric. To contribute this research endeavor, current project was conducted for dyeing cellulosic fabric via new hetero-functional reactive dyes R1 R2 synthesized our previous study. Optimization different process variables (temperature, salt, alkali concentration) their interactive study exhaust explored delineated based on a statistical tool response surface methodology. Results divulged that both displayed maximum exhaustion fixation at temperature 61.50°C Reactive dye exhibited 87.62 (±3) 82.85 percentage optimum salt (29.07 g/L) (32.55 dosage while 81.50 77.21 its optimized concentrations (22.84 g/L). All showed positive synergistic effect properties. Enhanced as compared may be accredited greater planarity less steric hindrance R1. Both presented superb color buildup showing good excellent fastness cotton Future perspectives comprised application assessment parameters these polyester (PC)
